how can i call both functions? i'd like to avoid using the 
module prefix vg.vgSetParameterfv if possible


Add to openvg:
alias vgSetParameterfv = vg.vgSetParameterfv;

same behavior when overriding methods of base classes


This is by design.

thx that works, but why is it even necessary?

same behavior when overriding methods of base classes

class Matrix(T)
{
  abstract const(T) opIndexAssign(const(T) val, int row, int col);
  Matrix!T opIndexAssign(T val, Tuple!(int,int) idx0, 
Tuple!(int,int) idx1)

  {
...
  }
}

class DenseMatrix(T) : Matrix!(T)
{
override const(T) opIndexAssign(const(T) val, int row, int 
col)

{
...
}

alias opIndexAssign = Matrix!T.opIndexAssign;
}

why not just make it callable without the alias?
